TWISTING AND WINDING MECHANISM.

\ Application filed To all whom it vita/y concern.-

Be it known that 1, CHARLES HUGH Mc- CALL, a subject of the King of Great Britain, and a resident of Banbridge, in the county of Down, Ireland, have invented certain new and useful Improvements in Twisting and Winding Mechanism, of which the following is a specification.

Hyinvention relates to improvements in twisting and winding mechanism, and especially to machines for twisting thread, cord, or twine.

The objects of my invention are to increase output, capacity, and speed of any given unit, to economize space and weight of moving parts, to reduce power necessary to drive the individual units and the whole organized machine, and to obtain an efficient, positive, and simple feed without injury to the substance operated on. I attain these objects by the devices described and claimed hereinafter and illustrated in the accompanying drawings, in which like figures of reference refer to like arts throughout the respective views.

Heretofore in twisting-machines there have been two principal forms of feeding devices for drawing the strands from cre'els and feeding the twisted product to the fliers. These have been, first, a series of rollers either independently or positively driven, between which the threads have been nipped or crushed while being fed. The other form is that embodied in a plurality of positivelydriven grooved pulleys on the flier itself, about which pulleys the cord is passed from one to another many times before passing finally to the flier-eyes. Among different objections to these methods two are especially clearin the first case, the injury to the fiber or thread itself by being crushed between the roller; in the second, the applying all the tension of the feed at one point, and that point at the flier, thus increasing the liability to breakage, &c.

By my device I am, among other advantages, enabled to feed the threads without injury to them and without danger of breaking the final product.

Figure 1 is a view, partly in elevation and partly in section, showing my improvement and so much of an organized machine as is necessary to explain the invention. a plan of the feeding device. view of a detail of guiding mechanism.

Referring to figures, 1 is the frame Fig. 2 is machine, on which are supported a plurality not pass.

l i l i Fig. 3 is a front ess takes Patented Dec. 26, 1905 of creels 2, from which the threads 3 3 3, are

led, passing through a separatingguide 4,

which keeps them separate and parallel, thence about a suitable deflector or guide 5 (preferably a rod of glass or other suitable material) in the water-trough 6.

7 is an eye or ring or other device through which the threads pass and by which they are drawn together and then pass about a second glass or other rod or suitable deflector or guide 8. From this point the threads are led about a driven wheel 9, the arrows indicat ing its motion. This roller or wheel regulates the speed of movement of the group of yarns or strands 3 3, which again pass from the driven roller about a third deflector and tension guide 10, after which they pass a second time about the driven wheel 9, passing once more about 10, whence they are led over a wheel or pulley 11. These rods or guides 4, 5, 8, 10, and 1 1 perform the additional function of creating and maintaining a tension upon the thread. I find it advisable to place the pulley 11 so that its periphery, where the thread is, shall be substantially in a line with and vertically over the axis of the spindle and flier. The group of threads now passes down through an eye 12, supported intermediate the pulley 11 and the flier 13, which acts as a threadplate, to the flier 13. On the flier 13 I place runners or pulleys 14 15, preferably grooved. The receiving periphery of the first one, 14, is placed as near the center of the spindle as convenient, so that there is little or no tendency for the threads 3 to balloon between the thread-plate eye 12 and the flier 13, the second pulley 15 is so placed as to prevent the thread from touching the head of the bobbin 16 on its way to the eye of the fiier 17, by which it is wound onto the bobbin 16 in the ordinary manner.

The operation of my device is as follows: Nhen the machine is put in motion, the driven wheel 9, placed at a point intermediate the water-trough and flier, draws or winds the thread strand about itself, constantly drawing off from the creels and passing on to the flier, whence it is wound on the bobbin, as is well understood, the act of winding the bobbin producing sufficient tension between the flier and wheel 9 to keep the strand tight and moving. The twisting procplace in that portion of the thread between the first pulley 14 on. the flier and of the the pulley 11, beyond which the twist does I may wind the threads one or -substantially more times around the driven wheel 9 in order to more thoroughly prevent slip and insure sufficient feed.

Where I have used the word about, I mean in part aroundthat is, not entirely encircling.

What I claim, and desire to secure by Let-' ters Patent, is

1. In an organized twisting and winding machine, a plurality of thread supplies, a separating and deflecting guide 4 for the thread, a submerged deflecting-guide 5 about which the threads pass untwisted; an assembling-eye 7 in line with another deflectingguide 8 a deflecting-guide 8 a driven feeding-wheel 9 and another deflecting-guide 10 about both of which the strand is twice led; a deflecting-pulley 11 nearly in line with the aXis of the flier; a thread-plate 12 interme diate the pulley 11 and the flier 13; and two deflecting-pulleys 14 15 on the flier 13; all arranged in the order specified, substantially as described.

2. In an organized twisting and winding machine, a plurality of thread supplies; a separating and deflecting guide for the threads; a submerged deflecting-guide, an as sembling-eye, a deflecting-guide adapted to be engaged by a strand before passing about a feeding-wheel; a feeding-wheel; a tensionguide about which and the feeding-wheel the strand passes a plurality of times; a pulley in line with the axis of a flier;

a thread-plate in line with and intermediate the pulley and the flier stantially as described.

and a flier, sub- 3. In an organized twisting and winding machine, a plurality of thread supplies; a separating-guide; an assembling-eye; a feedingwheel; a plurality of deflecting-guides,

about which and the feeding-wheel the strand separatinguide; a submerged deflectin guide; an assembling-eye; a feeding-whee a plurality of deflecting-guides about which and the feeding-wheel the strand is led; a defleeting-pulley substantially in line with the aXis of the flier; a thread-plate in line with and intermediate the pulley and the flier; and a flier, substantially as described.

5. In an organized twisting and winding machine, a plurality of thread supplies, a separating-guide; a submerged deflectingguide; an assembling-eye; a feeding-wheel; a deflecting-guide intermediate the wheel and the eye; a flier; a deflecting-pulley substantially in line with the aXis of the flier; a deflecting-guide intermediate the feeding-wheel and the pulley; a thread-plate intermediate the pulley and the flier, substantially as described.
